HENRY PENNIE, OF BROOKLYN, NEW YORK.

RUBBER HEEL.

SPECIFICATION forming part of Letters Patent No. 232,900, dated October5, 1880. Application filed August 8, 1879.

To all whom it may concern Be it known that I, HENRY PENNIE, ofBrooklyn, Kings county, New York, have i11- vented certainImprovementsin Rubber Heels for Boots and Shoes, of which the following is aspecification.

Figure 1 is a side view, partly in section, of a shoe provided with oneof my improved heels,- Fig. 2, a detached perspective view of the frame.

Similar letters of reference indicate corresponding parts in bothfigures.

This invention relates to improvements 011 rubber heels for boots andshoes, and has for its object to provide a secure and rigid attachmentof the rubber heel to the leather sole of the shoe; also, to prevent therigid fasteners which I found necessary from destroying the elasticityof the heel.

My invention consists, principally, in molding the rubber of the heelaround metallic spuds that are united into a frame and screwthreaded toreceive the fastening and connecting screws.

The invention also consists in further details, which are hereinaftermore fully pointed out.

In the accompanying drawings, the letterA represents the leather sole ofan ordinary boot or shoe. 7

B is the heel, made of india-rubber or equivalent elastic gum. Said heelis externally of the usual form of heels, but may be shaped asnecessity, convenience, or fancy may dictate.

Vithin the rubber heel is contained a frame, 0, of metal. or equivalentsubstance, of annular form, which frame has a series ofupwardly-projecting spuds or pillars, c a, of which three are shown inFig. 2 of the drawings; but any other suitable number may be used in oneheel. These spuds or pillars are provided with female screw-threads andadapted to receive the screws '0, that unite the heel to the sole A.

The frame 0, with the spuds a, is placed into the mold in which therubber heel is molded, and is entirely surrounded with, and in turnsurrounds, the rubber serving to anchor the spuds a securely within therubber heel, and to thus provide a safe fastening for holding the heelattached to the shoe or boot.

The screws 1) are inserted from above through holes in the sole A, andhave their heads sunk into said sole, which heads may be further coveredand entirely concealed by a piece of ch amois-skin or otherwise.

The treading-face of the heel I provide with a detachabletreading-plate, D, of leather or equivalent material.

The rubber of the heel extends above the upper ends of the spuds a, thuspreventing direct contact between the spuds a and sole A.

A cavity, g, is left in the upper part of the heel, within the compassof the frame 0, to save material and enhance the elasticity. The cavityextends farther into the heel than the screws 1), and thus assists inincreasing the elasticity of the heel throughout, which it could not doit, instead of an annular, a solid frame, 0, were used. This cavity ismade the receptacle of a spiral spring, h, as shown, which adds to theelasticity and strength of the heel.

I claim- 1. A rubber heel made of one single piece of rubber separatefrom the shoe, and 0011- taining within said rubber, so as to beentirely concealed therein, the open frame- 0, having the threaded spudsa, substantially as described.

2. A rubber heel secured detach-ably to the sole of a completed shoe orboot by metallic fasteners b, and provided within the rubber of the heelwith an open frame having metallic spuds a, all constructed so that therubher of the heel projects beyond and above the spuds, substantially asspecified.

3. The rubber heel B, containing metal frame 0, which connects with thefasteningscrews 1), and made with a cavity, g, within the said frame (J,all arranged so that said cavity extends farther into the heel than thescrews, substantially as specified.

4. The annular frame 0, made with two or more projecting hollow pillarsorspuds, a, each of said hollow pillars or spuds being threaded on itsinner side, substantially as and for the purposes specified.
